Born from Papaya (Oni Seeds) × Cookies Auto F5, this F5 sativa-dominant hybrid is a flavor-rich resin machine bred for extractors, flavor chasers, and growers who want fast premium results with minimal effort.

Fast Buds' Z-Up Auto is a sativa-leaning autoflower born from the fusion of the RS-11 cut and Auto Z F5, bringing an entirely new citrus-forward terpene profile to the table. The F5 edition is bright, loud, and full of energy, designed for daytime use, flavor hunters, and fans of all things fizzy and uplifting.

Ztrawberriez Auto is a Fast Buds next-generation polyhybrid bred from Strawberry Pie Auto, Z Auto, and Tropicana Cookies Auto — delivering up to 25% potency, yields of 600 g/m², and award-winning flavor in just 9-10 weeks. Winner of Best Sativa at the American Autoflower Cup 2024, she's a flavor-chaser's dream with a complex blend of fruity terpenes, rock-solid buds, and a perfectly balanced hybrid effect.

Auto Cinderella Jack is Dutch Passion's answer to the question of whether an autoflower can genuinely outperform photoperiod varieties on pure potency — and the answer is a decisive yes. With a THC percentage of nearly 26% verified by two separate laboratories using the HPLC method, this is the most potent autoflower in the Dutch Passion collection and arguably the strongest autoflower in the world at launch. The strain took 2nd prize at the Copa Esmeralda in Colombia in 2018, confirming what the lab analysis already showed. The genetic lineage is (Cinderella 99 x Jack Herer) x Magnum Genetics: two legendary photoperiod parents known individually for potency, flavor, and yield, crossed with the Magnum autoflower line from Buddha Seeds (which guarantees above-average harvests and contributes the auto genetics). The project started as a Cinderella 99 x Jack Herer hybrid, with Magnum auto genetics added to convert the line to autoflower. The result comes from many generations of selective breeding focused mainly on one characteristic: THC percentage. Only careful breeding by a skilled master breeder made this level of potency achievable in autoflower format, and the breeding program used professional laboratory analysis at every stage to ensure the high-THC genetics remained stable across generations and across individual plants. The terpene profile is dominated by alpha-pinene (pine), beta-myrcene (floral, earthy, fruity), beta-caryophyllene (spicy and woody), and limonene (citrus, fresh and fruity). Combined these produce a strong pine-like, spicy, and fruity aroma with some phenotypes expressing more fruit and freshness than others. The buds are super white, loaded with trichomes, and deliver a wonderfully tasty high that hits hard and lasts long — a unique combination of cannabinoid power and terpene complexity that separates her from generic high-THC strains.

Auto Ultimate is one of the best-yielding autoflowers in the world and, arguably, the highest-yielding autoflower in the Dutch Passion collection — a robust, vigorous plant that combines exceptional growth energy with generous harvest potential and a high-quality cerebral high. The genetics come from Dutch Passion's original photoperiod parent The Ultimate, which became a bestseller shortly after launch for combining extremely high yields with strong long-lasting effect. Auto Ultimate was created by crossing The Ultimate with the classic bestseller Auto Mazar, and the result inherited the extreme yield potential of its photoperiod parent in autoflower format. This strain has produced single-plant harvests of up to 1 kg of dry bud in expert setups, which is genuinely rare for any autoflower. The aroma mirrors the photoperiod Ultimate — dominant citrus and lime scent with sweet earthy notes developing during flowering, and after drying and curing the citrus becomes even more pronounced with strong lemon and musky character. Flavor-wise she compares to classic Lemon Haze and Lemon Skunk but with her own signature — some smokers pick up a coffee flavor on the exhale. The buds are monstrously big, most at least the size of a golf ball and completely covered in trichomes, carrying an old-school aroma reminiscent of Amsterdam coffee shop culture. Auto Ultimate is a popular strain among concentrate makers because large plants produce many sticky flowers that work equally well for cannabis oil, rosin, shatter, wax, or butter — the sheer biomass plus the terpene density makes her particularly effective as an extract base.

Blueberry Bubblegum Automatic was developed by crossbreeding Gelato #420 with Sunset Sherbet to create an 80% indica, 20% sativa autoflowering cultivar. During flowering she expresses vibrant shades of green and purple, and the indica-dominant expressions result in compact plant structure with a short flowering period. The strain can be grown indoors in tents or outdoors in temperate and continental climates, which is a broader climate tolerance than many autoflowers offer. Plants produce a soothing full-body buzz paired with explosive flavor, and the low-profile growth pattern suits growers with space constraints or discretion requirements. Mario Guzman, who works under the name Sherbinski, is credited with breeding both Gelato and Sunset Sherbet — Gelato has become the backbone for many of the currently popular US-market strains, and that lineage runs directly through this autoflower.

Dark Devil Auto is Sweet Seeds' hybrid between the incredible Big Devil XL Auto and an exotic autoflowering strain with purple flowers. The purple characteristic is inherited from ancestors from the Chitral region in the Pakistani Hindu Kush near Afghanistan, which contributes faster flowering while bringing sweet aromas and purple colors. Dark Devil Auto shows strong hybrid vigor from germination — plants grow with the appearance of Indica-Sativa hybrids featuring a strong central stem, numerous side branches, and a big main cola. Resin production is abundant both in flowers and surrounding leaves, and the aromatic signature combines sweet and fruity character with incense hints and delightful citrus tones.

Gorilla Cookies Auto is Fast Buds' most awarded and best-selling autoflower of all time — a powerhouse fusion of GG4 Auto F6 × Cookies Auto F5 bred to deliver extreme potency, dense yields, and mouthwatering flavor in a fast easy-growing format. Now in her F6 generation, the strain has earned her reputation through real commercial and competition performance. She grows stout and bushy, reaching up to 150 cm with thick branches and a sturdy main cola. Expect golf-ball-sized buds absolutely coated in trichomes, producing up to 650 g/m² in around 10 weeks. Late in flower the buds turn almost white from resin, making her a top pick for extractors and commercial growers alike.

Fast Buds' Gorilla Auto is the most infamous strain in the catalog — a knockout artist with a staggering 24% THC, large plant size, and buds so loaded with resin that the "glue" in her name becomes literal: fingers will stick together during trim. She's a super-easy grow with a pine and diesel terpene profile that impresses even experienced cannabis connoisseurs, and the 9-week cycle produces enormous sticky fat buds that any type of grower will fall in love with. Well suited for beginner growers, and hash makers should not miss out on this trichome queen.

Fast Buds' Girl Scout Cookies Auto is one of their best-selling and most renowned strains — a 20% THC cultivar with extra-large yields and the fantastic sought-after cookie flavor that made the GSC family famous. The Cali cookie genetics are a cinch to grow indoors or out, producing dense sparkling nugs. A huge-yielding sticky resin machine.

Guava Auto transforms the growing process into an absolute pleasure — a balanced 50/50 hybrid autoflower with exceptional resilience against pests and mold, coupled with remarkable yield potential of up to 550 g/m² in just 8-9 weeks. Perfect for novice cultivators and those with busy schedules. With 28% THC content, brace yourself for a gradual yet powerful onset that seamlessly elevates mood to pure bliss. As consumption progresses, experience uplifting euphoria that enhances sociability and chattiness to unparalleled levels.

A coveted choice for hash makers and extractors, this strain not only tantalizes taste buds but ensures substantial returns on flower-to-rosin conversions.

Quick One is RQS's answer to the most basic autoflower request: small, fast, stealth-friendly, no-fuss. The cross is Lowryder 1 (the original stable autoflowering workhorse) x Old School Indica (for body stone and yield). The pairing prioritizes reliability over complexity - Lowryder 1 gives the speed and predictability, Old School Indica adds enough density and flavor to keep the end product from being a compromise. After crossing and stabilizing, RQS landed on a consistently fast, compact plant aimed squarely at first-time growers, stealth grows, and guerrilla setups.

Royal AK Auto is the autoflowering reinterpretation of the original AK-47 hybrid — one of the most recognizable strain names in commercial cannabis. The lineage pulls from the same pool of Colombian, Mexican, Thai, and Afghan landraces that defined the AK character: hardiness, resilience, and a sweet-floral nose that set the strain apart from the heavier-indica skunks of its era. RQS's auto version adds ruderalis genetics for rapid cycle times without sacrificing the giggly, daytime-friendly effect of the original. Genetic split sits at 40% indica, 35% sativa, 25% ruderalis — an unusually balanced distribution for an autoflower, and one that preserves the AK-47 experience rather than substituting a generic auto profile for it. For growers who want AK character without the photoperiod commitment or the multi-phenotype lottery of traditional polyhybrid seed packs, this is the closest commercial match available.

Royal Cheese Auto is the autoflowering version of the legendary UK Cheese line — a strain bred in Britain for its notorious pungency and tranquil, munchy effect profile. RQS built their auto version by crossing Cheese into Royal Critical Auto, which contributed the short cycle and euphoric lift of a Cannabis Cup-winning autoflower. The result is a 50% indica, 30% sativa, 20% ruderalis split that preserves the skunky cheese aroma while cutting weeks off the timeline. For growers chasing Cheese character without the full photoperiod commitment, this is the cleanest shortcut RQS offers, and the phenotype expression stays close enough to the original UK Cheese that veteran growers recognize the lineage immediately.

Fast Buds' Stardawg Auto brings the prized Chemdawg #4 x Tres Dawg cut into collision with Fast Buds' unique autoflowering genetics, giving rise to a new breed of robust Sativa-Indica hybrid that performs as an all-star for growth, taste, and a tasty 22% THC. Novices may want to watch out — the potency is higher than many first-time growers expect from an autoflower.

Super Boof XL Auto is Sweet Seeds' 10th Generation extra-large autoflowering hybrid — a cross combining the abundant resin production of Super Boof with the exotic tropical profile of Papaya Zoap Auto. The balanced cross produces compact, well-branched, vigorous plants with dense chunky buds coated in a thick trichome layer, making her ideal for all types of extractions. The aromatic profile blends ripe cherry, sweet papaya, cookies, Diesel, and a floral background — a genuinely complex layered signature that separates her from typical single-focus modern hybrid autos. The effect is powerful, euphoric, and relaxing, perfect for stimulating conversation, creativity, and peaceful disobedience — a delicious tropical dessert made to be shared.

Sweet & Sour Cream Automatic has an indica-dominant lineage inherited from Sour Florida OG and Gelato #420 — a strain launched as part of Sensi's Research project. Plants develop sturdy branching, short internodal spacing, and dense bud formations, and the flavor profile includes creamy undertones with a sour lemon and diesel tinge that separates the strain from typical dessert-leaning autos. Large yields of highly resinous flowers are possible indoors and outdoors in temperate and continental climates. Sour Florida OG hails from Florida — a geographic and genetic origin that's important to the flavor character — while Gelato #420 was created by White Label Seeds by crossing Gelato 33, Durban, and Hindu Kush, which gave the strain the creamy Gelato character paired with a more grounded indica backbone than straight Gelato crosses produce.

Titan F1 is RQS's flagship entry into F1 hybrid autoflowering genetics - a new breeding category that crosses two stable inbred lines to produce uniform, high-vigor offspring with predictable traits across every seed. The parental lines for Titan share heritage with Blue Dream, Sugar Magnolia, and Amnesia, which gives her an unusual mix of fruit-forward terpenes and the kind of structural resilience commercial growers actually need. As one of the first true F1 autoflowers on the market, she's aimed at growers who want uniformity and predictability from seed rather than the phenotypic lottery of traditional polyhybrid autoflower packs.

Tropicanna Cherry XL Auto is Sweet Seeds' 5th Generation extra-large autoflowering hybrid — combining the potency of Tropicana Cherry with the exquisite genetics of Tropicanna Poison XL Auto, renowned for floral beauty, abundant resin production, and exotic aromatic profiles. The strain produces sleek vigorous plants with long lateral branches and large compact buds covered in trichomes, making them perfect for high-quality extractions. Deep green tones blend with orange pistils and reddish hues toward the end of flowering. The aromatic profile fuses citrus notes with ripe cherry and blood orange, sweet cookie nuances, and a spicy background. The effect is powerful, uplifting, and stimulating — ideal for enhancing creativity, good spirits, and conversation.

Wedding Cheesecake Auto is Fast Buds' rapid-flowering balanced hybrid — a highly productive 24% THC cultivar that needs only about 9 weeks from seed to harvest. Rich in THC, terpenes, and a medium height makes her ideal for beginner growers and especially those with shorter summers. Impressive trichome production, strong resistance to colder weather, and excellent performance both indoors and outdoors. Expect phenomenal flavors combining vanilla cookie dough, earthy and creamy notes, plus sweet aromatic overtones of baked fruit tart. The buds are chunky, large-sized, and covered in trichomes, sparkling with an array of colors from bright green and lime hues to hints of magenta and purple. Tightly clustered calyxes make the buds dense and firm to the touch. Broken buds release a sweet cheesecake aroma with sweet earthy background.
